THE THIRTEENTH COLLOQUIUMFEST Speaker: Josnei Antonio Novacoski (University of Saskatchewan) Title: Reduction of Local uniformization to the rank one case Abstract: The main result in this talk is that in order to prove the local uniformization theorem for local rings it is enough to prove it for rank one valuations. We prove also the reductions for different versions of the local uniformization theorem. Our proofs do not depend on the nature of the class of local rings for which we want to prove local uniformization. This is a joint work with Mark Spivakovsky.
